Glad you like that 10mm. I've had mine for about a year now, and here is what I have found.
1. Like loudernhel said, the gun is WAY undersprung. The bigtime teardrop primer indentations were a real indication. I ordered a Wolff 22lb spring and it works well. I e-mailed the company and received a very friendly reply explaining that even the 22lb. spring was a little light for full 10mm loads, and they were planning to develop a stronger spring, but it was a little low on the priority list. They said that many had used the 22lb spring and were happy. My experience has been similar.
2. When I first got the gun, it malfunctioned pretty consistently. Even after a break in, it would still malf. quite often. On the Glocktalk 10mm forum, I was informed that it might be the magazine, because thedesign had been changed. I e-mailed EAA, and within a couple of days I had a new red follower to replace the old black one. The gun hasen't hiccuped since.
I really want to do some work on it, like dehorning job, installation of SA trigger, and adjustable sights. I just need to find someone to do the work.
Good shootin,
